DENTAL ADHESIVE Russian patent published in 2022 - IPC A61K6/15 A61K6/884 A61K6/887 C08L33/10 

FIELD: dentistry.

SUBSTANCE: group of inventions relates to dental adhesive and a method for unsticking polymerized dental adhesive. The proposed dental adhesive contains at least one polymerizable monomer, a polymerization initiator and thermally expandable particles containing a shell encapsulating an expanding additive, while shells of thermally expandable particles are made of copolymer of acrylonitrile and methyl methacrylate. The mass content of thermally expandable particles ranges from 10% to 45%. A method is also proposed for unsticking the above-mentioned polymerized dental adhesive attached to the tooth surface, where the mentioned polymerized adhesive contains at least resin and thermally expandable particles having a shell made of copolymer of acrylonitrile and methyl methacrylate, and an encapsulating expanding additive, where polymerized adhesive is unsticked by exposing it to ultrasonic vibrations.

EFFECT: use of the claimed dental adhesive makes it possible to unstick polymerized adhesive at the end of treatment in a way that is simpler and more comfortable for a patient, in particular, as a result of reducing the risk of burns and damage to dental tissue.
